Solution
Solution Steps
To determine whether the statement makes sense, we need to understand the relationship between the number of bars in a bar graph and the number of data categories. A bar graph typically has one bar for each data category. Therefore, if there are 8 bars but only 7 data categories, it suggests an inconsistency, which could indicate an error in the graph.
Step 1: Understanding the Problem
We have a bar graph with \( \text{num\_bars} = 8 \) and \( \text{num\_categories} = 7 \). The relationship between the number of bars and categories is crucial for determining the validity of the statement.
Step 2: Analyzing the Relationship
In a bar graph, each data category typically corresponds to one bar. Therefore, the expected condition is:
\[
\text{num\_bars} \leq \text{num\_categories}
\]
In this case, we have \( 8 \nleq 7 \), indicating that the number of bars exceeds the number of categories.
Step 3: Conclusion
Since the number of bars exceeds the number of categories, the statement that the bar graph must be wrong makes sense. Thus, the correct interpretation is that there should be fewer bars than categories.
